' To all whom it may consem:

Be it known that I, WILLIikIlI A. SAUN- nilns, a citizen of the UnitedStates, residing at Jamaica Plain, in the county of Sufiolk and State of-Massachusetts, have invented new and useful Improvements inCarcass-Splitting Machines, of which the following is a specification.

' This invention relates to improvements in sawing machines andparticularly to a machine for sawing or, in other words, splittingcarcasses ofhogs or steers, and has for its object to provide a rapid,efficient and'conveniently operated machine for sawchine of this classin which there shall be practically no time lost in the operation of themachine, as would be the case if a s1nthat by employing a plurality ofsaws act-- ing successively the return motion of the saw which would benecessary with the use of a single saw, is obviated.

To these ends, the invention consists in the novel features ofconstruction and in the. combination and arrangement ofparts set forthin the followingspecification and particularly pointed out in theclaims.

Referring, to the drawings: Figure 1 is a plan of a carcass splittingmachine em.- bodying my invention. Fig. 2 is a front elevationoftheinachine. Fig. 3 is a side elevation viewed from the right hand,side I of Fig. 2. Fig. 4 is a sectional view taken on line 44 of Fig. 2,looking toward the left. Fig. 5 is anenlargeddetailsectional View of oneof the saws and its arbor taken on line 55 of Fig. 2, looking toward theleft.

Like numerals refer to like parts throughout the several views of thedrawings In the drawings, 5- is a saw carrier whichmay be. mounted tomove upon a suitablesupport and which ,is preferably journaled .upon apair of supports 6 and 7 which are preferably provided, respectively,bosses 8 and 9 projecting into hubs or trun nions .10 and 11,respectively,provided on the saw carrier 5. J ournaled on the sawcarrier 5 is a saw or a plurality of saws, preferably the latter, and inthe present instance'there are shown twosaws 12 and 13 secured to arbors14 and 15,.respectively, journaled in suitable bearings on the sawcarrier These saws are mounted in one and the same vertical plane sothat by rotating the carrier 5. the saws may be caused to operatesuccessively upon the successive carcasses as the same are placed inposition to be operated upon. The carcasses may be placed on anysuitable support, but for this purpose there is preferably employed arotating support 16 mounted to rotate about a vertical axis and having aplurality of wings 17 forming compartments 18, so to speak, in which thecarcasses may be placed andheld during the splitting operation, one ofthe carcasses being shown in such position in Figs, 1 and 2. VVhile oneof the carcasses is being operated upon by the saw, others may be hungin the next succeeding compartment 18 of the rotating support 16 readyto be brought with preferably into position to be operated upon by thesaws simply by rotating the support 16 the required'distance.

In order that the rotating support may be firmly held against rotationduring the splitting operation, there is preferably. em-

ployed' a means to lock the same in a series of predetermined positions,such means preferably consisting of a locking plate 19 provided with aseries of notches '20 corresponding in number 'to the compartments 18,which notches are arranged to receive a locking key 21 provided on alever 22; The,

lever 22 is mounted on a pivot 23 on a suit-' able support 24 and is soarranged that by. lifting the outer end of said lever the key 21 may bewithdrawn from the particular .notch 20 in which it islocated, thuspermitting the holder 16 to be rotated the required amount and locked.

The saws 12 and 13 are driven by any suitable nieans such, for example,as belts 25 and 26, respectively, passing around pulleys 27 and 28secured to the arbors 14 and 15, respectively, said belts being drivenby pulleys 29 and 30,. respectively, secured to a driving shaft 31journaled in suitable bear;

34 is journaled concentric wit-h the axis of the supports 6 and 7 andthe idler pulley so arranged with relation to the idler pulley 34 that asubstantially uniform tension of the belt 32 is maintained during theswinging of the supports 6 and 7 to and fro.

A rotary motion is imparted to the carrier 5 by suitable meanspreferably consisting a worm gear 39 secured to the hub 10 of saidcarrier and meshing with a worm 40 secured to a shaft 41 journa-led insuit able bearings on the support 6, said shaft being'preferably drivenfrom the driving shaft3l by suitable driving connect-ions preferablyconsisting of a belt 42 passing around a pulley 43 secured to the shaft31, around two idler pulleys 44 and 45 journaled on the support 6, andaround a pulley 46 secured to the worm shaft 41.

It will be understood that by the mechanism just described be rotated ata' high rate of speed and the carrier 5 may be revolved slowly by theuse of the worm and worm gear driven by the driving shaft 31 so that thesaws are brought successively, into operation by the rotation of thecarrier the arrow a, Fig. 2.

The supports 6 and 7 are preferably mounted in such a manner as toenablethe operator to move the same laterally so as ally supported upon aframe 47 mental gears 54 an to changethe path of the saw from thecircular path which it would otherwise have to a path which .will'followthe shape of the backbone of the carcass and for the supports 6 and 7are preferably pivothaving two side members 48 and 49. Preferably theside members 48 and 49 are provided, respectively, with bosses 50 and 51constituting pivots projecting into hubs 52 and .53, respectively,provided on the side members 48 and 49,

Suitable means are provided for moving the supports 6 and 7laterally'during the operation of the saws. and for this purpose thereis preferably 55 secured to said supports,- respeotively, and meshinginto pinions 56 and 57, respectively, secured to shafts 58 and 59,respectively, jounraled in suitable bearings on the side members 48 and49-of the frame'47. In order that the pinioins 56 and 57 maybe driven'inunison, I provide suitable driving connections between the the saws 12and 13 may" 5 in the direction of.

' carcass into the this purpose.

. of the rotary rovided a pair of segshafts 58 and 59 and in the presentinstance for this purpose, I provide a shaft 60- journaled in the sidemembers 48 and 49 and passing through the bosses. 50 and 51, this shaftbeing connected to the shafts 58 and 59 by suitable gearingprefera-blyconsisting of two miter gears 61and 62 secured to the shaft 60 andmeshing with miter gears 63 and 64, respectively. The gears 63 and 64are secured to vertical shafts 65- and 66, respectively, journaled onthe side members 48 and 49 and having secured thereto at their upperends miter gears 67 and 68 meshing with miter gears 69 and 70 secured tothe shafts 58 and 59, respectively.

Secured to the shaft 58 is a suitable hand wheel 71 convenientlyarranged so that the operator may stand in a convenient position to viewthe action of the saws upon the carcass and may control the path of eachsaw by rotating said hand wheel in the proper direction, thus swingingthe supports 6 and 7 to and fro according to the path which it isdesired the saw shall take. The lateral movement of the supports 6 and 7is limited y a pair of studs 72 and 73 secured to said supports,respectively, and projecting through slots 74 and 75 provided in theside members 48 and 49, said studs also serving to prevent any lateralspringing of the supports 6 and 7, as will be evident by an inspectionof Fig. 4.

Having specifically described the I will now operation.

The carcass to be split isplaced in one of the compartments of therotatable supports 16 and said support is rotated to bring the properposition to be operated upon by one of the saws. While this positioningof the carcass is taking place, it will be understood that the sawcarrier 5 is proceed to despribe its general in a vertical or nearlyvertical position so that by the time the carcass has been properlypositioned ready to be operated upon,

one of the saws will swing'around into such a position that the operatormay cause it to begin its cutting operation by manipulating the handwheel so as to advance the saw into the Work and as the saw descends byreason motion of the carrier 5, the hand wheel is manipulated in theproper manner to carry the saw into ,the correct path to:-'cut throughthe backbone of the carcass. By the time that this has taken place, thesaw has descended pretty well. toward the floor and while the motion ofthe saw carrier continues the rotatable support 16 is rotated a partialrotation, bringing another carcass previously placed in the machine, 1

next succeeding compartment into the proper position to be operated uponby the-next saw in the same manner in which the previous carcass wasoperated upon by the other saw.

Havingthus' described my invention,

to secure is:
